Which of the following statements is correct? a. If a firm uses the discounted payback method with a required payback of four years, then it will accept more projects than if it used as its cutoff criterion a regular payback of four years. b. For independent projects, the NPV, IRR, MIRR, and discounted payback (using a payback requirement of three years or less) methods always lead to the same accept/reject decisions for a given project. c. For mutually exclusive projects with normal cash flows, the NPV and MIRR methods can never conflict, but their results could conflict with the discounted payback and the regular IRR methods d. Multiple IRRs can exist, but not multiple MIRRs. This is one reason some people favour the MIRR over the regular IRR
